摘 要:針對(duì)目前我國可再生能源占比逐步增加,而整體利用效率不高的問題,提出了將電動(dòng)汽車作為主動(dòng)負(fù)荷,消納微網(wǎng)中可再生能源的經(jīng)濟(jì)調(diào)度模型,利用遺傳優(yōu)化算法求解經(jīng)濟(jì)調(diào)度模型。研究表明電動(dòng)汽車的接入以及可再生能源的使用不但可以節(jié)約微電網(wǎng)的投產(chǎn)資金與運(yùn)行維護(hù)費(fèi)用、減少環(huán)境污染,還能夠充分發(fā)揮電動(dòng)汽車作為主動(dòng)負(fù)荷起到削峰填谷的作用,提高了微網(wǎng)的經(jīng)濟(jì)性。
關(guān)鍵詞:電動(dòng)汽車;微網(wǎng);可再生能源;主動(dòng)負(fù)荷;智能電網(wǎng)

Abstract: Aiming at the problem that the proportion of renewable energy sources in China is increasing gradually, but the overall utilization efficiency is not high, this paper proposed the economic dispatch model to take the electric vehicle as the active load to consume and absorb the renewable energy sources and the genetic algorithm was used to solve the economic dispatch model. The research result shows that the access of electric vehicles and the usage of renewable energy sources not only save the production and operating maintenance cost of microgrid and reduce the environmental pollution, but also give full play to the peak clipping and valley filling functions for the electric vehicles as active load, which improves the economy of microgrid.
Key words: electric vehicle; microgrid; renewable energy sources; active load; smart power grid
